Overview: The THIEL SCS4 is a 2-way loudspeaker that performs equally well as an excellent full-range stereo pair, surround-sound, or center-channel speaker. It's coaxially-mounted drivers and aluminum baffle contribute to the SCS4's outstanding fidelity, making it as comfortable in demanding music systems as it is playing movie soundtracks or background music.

Driver Technology

Coaxial/Coplanar Driver: The THIEL SCS4 utilizes Coaxial/coplanar driver mounting for correct time response delivers full-range performance with vertical, horizontal, shelf, or stand placement. The SCS4 uses a very low distortion, high output, metal diaphragm 6.5-inch woofer that is coaxially mounted with a 1-inch, high output metal dome tweeter, the same high performance tweeter that is used in THIEL's flagship model CS3.7. The woofer's short coil/long gap, copper stabilized motor system greatly reduces distortion, and its reinforced metal diaphragm is specially shaped to reduce diffraction of the tweeter's energy. In addition, the SCS4's unusual coaxial driver mounting allows great placement flexibility by ensuring that every listener hears the sound from both drivers at exactly the same time, regardless of where and in what orientation the speakers are placed.

Crossover Network: The SCS4 delivers complete phase coherence for exceptional clarity, transparency, and three-dimensional imaging thanks to its crossover network. The SCS4's crossover is a true first order acoustic type that provides the utmost in spatial and depth imaging performance as well as overall realism. This is the only type of crossover that provides complete accuracy of amplitude, phase, time, and energy, and therefore the only type that does not distort the musical waveform. Proper application of this gradual-transition type of crossover requires the use of more expensive drivers with wider frequency ranges than are required for use with common quick-transition crossovers but the benefits also include improved uniformity of the speaker's output in all directions. The SCS4's crossover is meticulously engineered to achieve extreme tonal neutrality and is constructed with extensive use of polypropylene and custom polystyrene capacitors.

Time and Phase Coherent: As with all THIEL loudspeakers, the SCS4 is completely time and phase coherent for much greater sonic realism. THIEL's Coherent Source technology achieves the elimination of both time and phase distortions that cause alterations in the reproduced musical waveforms of most loudspeakers. Eliminating these distortions results in enhanced realism, clarity, transparency and immediacy as well as improved imaging and soundstaging in both the lateral and depth perspectives. Phase coherence in the SCS4is achieved by utilizing a sophisticated first-order electrical crossover system in conjunction with unusually wide bandwidth drivers. Time coherence is achieved by placement of its Coaxial/Coplanar driver on its baffle that is sloped at the correct angle to cause the sound energy from each to reach the listener at the same time.

Enclosure Design

Compact Bass Reflex Cabinet: The SCS4 utilizes an aluminum baffle, doubly-laminated 1-inch cabinet walls, and thick bracing to create an extremely rigid cabinet to eliminate unwanted resonances. The cabinet plays an enormously important role in the quality of music reproduction and so the engineering of the SCS4's cabinet incorporates several innovations that contribute to the speaker's stunning clarity, its utter tonal neutrality and its exceptionally realistic imaging. The SCS4's new cabinet design uses a die-cast aluminum baffle for much greater rigidity in driver mounting and elimination of cabinet resonances. Combined with doubly-laminated 1-inch cabinet walls, unified and reinforced with thick bracing, this robust cabinet construction, usually only found on much more expensive speakers, greatly improves detail, clarity, and spatial information. The SCS4 is available in real wood Natural Cherry and Black Ash finishes

Note: THIEL wood cabinets possess a high quality lacquer finish that is both beautiful and durable. However, any wood finish can be damaged by excessive moisture, dryness, or direct sunlight. When cleaning your speakers, avoid using oils, waxes, or polishes that contain silicone.

Grilles: The SCS4's steel grille frame is designed to not produce diffraction so there is no sonic reason to remove it. If you do need to remove the grille, pull the grille frame away from the speaker while gripping both sides (long) of the grille frame.

Connections

Connections: The SCS4's input terminals are located on the rear of the speaker cabinet. The SCS4 uses binding posts that accept several types of wire connections (will not accept dual banana plug connectors but single banana plugs can be used). The input terminals are designed to be easily tightened by hand or a 1/2 inch nut driver can be used. The speaker's input terminals are color coded to facilitate that both speakers in a stereo system are wired in the same polarity for maximum speaker performance. The speakers should be connected to the amplifier with high quality cable to ensure minimal loss of power and proper control by the amplifier.

Note: The SCS4 is a very high quality sound reproducer and will benefit from use with the best associated equipment. Since it is extremely accurate, it will reveal sources of distortion generated elsewhere in the system. For example, distortion resulting from poor recordings or inferior electronics will be reproduced accurately. Also, the quality of the interconnect cables and speaker cables will significantly effect the performance of the system

Power Requirements: It is important to have enough power to play at the level you desire without distortion. If high sound levels are desired, the SCS41's are designed to be used with amplifiers rated up to 200 watts per channel (into 8 ohms). Since the SCS4 provides a 4 ohm load to the amplifier, it is important that the amplifier be rated to deliver at least 50 percent more power into a 4 ohm load than it does into an 8 ohm load. The SCS4 is of average efficiency (88dB) and therefore can achieve average output levels with an average amount of power.

Mounting Options

Speaker Placement: The SCS4 is specifically designed to give a high level of performance from a variety of room locations and positions. They can be placed on bookshelves or on stands, and oriented horizontally or vertically while still providing a degree of realism not usually obtainable under unusual or difficult placement conditions. Because the SCS4 is magnetically shielded, it can be placed on or near video displays without causing picture distortion.

Warranty Information & Break-In Period

Break-In Period: The SCS4's, like most speakers, require a period of playing before they perform optimally. The amount of time depends on how loudly the speakers are played; more time is required if played softly, less if played loudly. At least 50 hours at moderately loud levels are required before the speaker is performing near optimum. You should notice even more improvement after 100 hours of playing.

10 Year Warranty: THIEL warrants every THIEL model SCS4 loudspeaker against defects in materials and workmanship to the original owner for a period of ten years from the date of purchase. THIEL will, at no charge, replace any defective part and make any repairs necessary to ensure its proper performance when the defective unit is returned to us postpaid. This warranty does not cover damage due to accident or abuse and is void if the unit has been tampered with. This warranty is automatic and no registration is required.
